While a lengthy song with an unchanging beat isn't an inherently bad idea, Buckethead chose the single most annoying drumbeat of all time to carry a 45-minute tune. Furthermore, he clearly put no real thought into this-- it's an improvisation, but not a very good one. It sounds as though he played the beat, half-heartedly jammed over it with one eye on the clock, stopped at the 45-minute mark, and released the song without listening back.
